Damasco Mar. 2, w15'.

To al' wfzom it may; consom Be il: roown che@ l', Sara P. Mmm, citizen of che United States, reading ai: Navasotc, in the county of Grimes arid State of Texas, have invented certain new and vuseful Improvements in Crossovers, of which che following is a specication, reierence being had to the accompapying drawings.

This 'invention relatesto certain improvements in cross-overs for railways cod the object ci che invention is to provide a deviceore this general character wherein means ci a novel and improved character are provided to efreciually prevent a collision of trains traveling 'oa che icrsecting crack Ways.

The invention oonsisis .ia the detailsmo' construction and in the combination and arrangement of che several paris whereby certain im lortaiii; advantages are attained and the device lis rendered simpler, less experisive and otherwise more conveniens and advantageous for use, alias Will be hereinaier more fully set forth.

The novel features of ehe im'eiiion will be carefully defined in the appended claim. n order that my inventioo may be better understood, l will now proceed to describe 'ne same with reference to the accompany ing drawings, wherein Figure l is a diagraplcc View of a crossover constructed in accordance with an embodiment of my inventiong' Fig. 2 is an Venv largcd sectional View iilustraiog the form of Contact employed in my invention as herein set forth; Fig. 8 is an enlarged sec tional View iliustraing a means forv coniroiling a switch; and Fig. i is an enlarged sectional 1rievv' illustrating. a means for operating a signal as herein embodied. A As disclosed in the accompanying drawings, 1-1 denote the intersecting track Ways, each ci which is provided co either side of the second track way with a branch iraclr 2 in communication with che main irac; line shroogli the medium cele. smitable switch 3, she construction an operation or which forming in its Adetails no particular feature of he present invention other than so stae that such switch isadapted to be operated through the mo'iufi of an arm l onder control o a double acting solenoid 5, as particularly shown in Fig.

3, adapied to oc properly opcraized 'upon nais 8, each vherein.,shown in the form of a semaphore as generally employed "in connection with railways, and each ofthe semaphores 8 is suitably actuated, as indicated' in Fig. 4, by e. double 'actixig solenoid 9 under control of the windings l0 and il, the windings l@ serving co cause che aci/nophore to be elevated when the adjacent switch 3 is opened and to drop or ali when such switch B ie adjusted into closed cosition.

Ae predetermined points on each of the main crack ways 1 and to opposite sides ci the. intersecting crack way and in advance of the switches 3 are the circuiiV closers 12 adapted to be compressed by a suitable shoe or other means carried by the craie co compete suoli circuits as wili energize ilie amper windings 6 and l@ whereby signal will be given by the proper semaphores 8 that a train on the second track is about to make a cross-over and 'to assure the passing of a train which may ignore the signal.A

onto a branch 2 whereby it will be readily perceived that the possibility of a collision is effectively and aueoma'icaliy guarded against. `While l prefer to employ a branch it is to be understood that a deraiiing switch may be used.

To either side of the atersccing track ways l and interposed between the switches 3 and lie track Ways l are the addiionel circuit closers 15 which are also adapted to beengaged by a suitable shoe or other means carried by a train passing over'eithcr of @bho track Ways and serving to energize the windings 7 and liwloereby ehe switches are adjusted to their normal positions or ciosed relaiire to the main line and the semaphores caused to drop citer a train has made the cross-over. The circuit closets l5 are identical with tiie circuit @losers 12-and may be constructed as indicated in detail Fig. 2. The particular manner whereby che seyerai circuit closers and operating means for the switches and semaphor ere conrolled forms no particular part of my iaaeaion as herein embodied, and it is not believed io necessary to disciosc the same other einen ifo say ihat such devices are scitabiy connected in' multiple from the source ,of electrical energy, as indicated vat 16.A i, 'The circuit elosers 12 "and""15"'are,v as herein disclosed, substantially identicaliin Aconstruction and for this reason it is tliou'gliu that ,e description 0f, erle. will sufgim beth. Asdieiosedsaftrwiar1y ifi --thecircuit closer 12, therein illustrated, coziprises the two contact members 17 and 18 in Flgi; 2,

electrical connection with tlie source 'of electrical 4energy 16 through ithe conductors,

the contact 17 being movable-relative to 'the contact 18 and, 'as herein disclesedgiictm'- prises a 'spring plate adapted to be engaged .by the inner extremity 119 of the arm -20 -Pimtfluy Supported, as, at 21, inerme-aim of its length,fthe opposite end 22 thereof terminating in. close proximity to'atrack- W'ay fl and adapted to be depressed bythe wheels .of a train passing over' 'such trackivay, as is beliewjed `to lbe self-evident.

'. From-the foregoing it is'thought to be obvious that. across-over' constructed in accordance ,'with my invention` is of an e`xtreme/ly simple and comparatively' inexpensive nature and is particularly Well adapted for .'use' by reason of the eilective meunierI y lnwhieh it isca-used-to operate to prevent collision of trains passing over lintersectin lines, and itV will also be obvious that 'my invention 1s susceptible of some change and cdiflcation'; gyithont 'material departure the fincil's and .Spirit thereof .crit-his reason 'do not wish tobi; understofodas limting'my'self. to the precise ar- 35v rangernentand formation of t {segerpl parte herein ,showny in carrying Oz '!.i"'ihv vention`-in practice;
